The purpose of this paper is to contribute to the mathematical treatment of hierarchies of decision-making systems as given e.g. by Mesarovic e.a. in [1]. This will be done by making explicit in the formalization of the relevant concepts a few aspects which in [1] were supposed to be implicitly understood, and had to be kept in mind to distinguish ...

On prefetching in hierarchical caching systems
IEEE International Conference on Communications, 2003. ICC '03., 2004Hierarchical caching is deployed to scale up the explosive Web growth, and the expiration-based mechanism is adopted as an economic means to support the weak consistency in this context. However, given a hierarchy, the user perceived performance heavily depends on its position.

Differentiations in Hierarchical Fuzzy Systems
2018Hierarchical fuzzy systems are one of the most popular solutions for the curse of dimensionality problem occurred in complex fuzzy rule based systems with a large number of input parameters. Nevertheless these systems have a hidden inaccuracy and instability problem.

Modeling of hierarchical fuzzy systems
Fuzzy Sets and Systems, 2003A new kind of mapping rule base scheme is proposed to get the fuzzy rules of hierarchical fuzzy systems. The algorithm of this scheme is developed such that one can easily design the involved fuzzy rules in the middle layers of the hierarchical structure.

Revisiting hierarchical quorum systems
Proceedings 21st International Conference on Distributed Computing Systems, 2002In distributed systems, it is often necessary to provide coordination among the multiple concurrent processes. Quorum systems provide a decentralized approach to provide such coordination that is resilient to node and communication link failures. Quorum systems are highly available and may be used to balance the load among the elements of the system ...

Dynamics in Hierarchical CSCW Systems
2003Computer supported cooperative work (CSCW) is a popular research topic in recent years. In classical cooperative applications, cooperation cannot be adapted to the dynamics and hierarchies of real world. According to the formal specification of dynamic cooperation in hierarchical systems, a dynamic hierarchical cooperative system model, DHCSCW, is ...

The ral hierarchical control system
Proceedings. 1986 IEEE International Conference on Robotics and Automation, 1986A Hierarchical Control System with organizer, coordinator and hardware levels has been developed. A VAX-11/750 serves as the organizer. An LSI-11/23 equipped with FPF11 floating point processor is the basis of the coordinator. The original controller for a PUMA-600 robotic manipulator has been modified to serve as the hardware level.

Mode Condensation in a Hierarchical System
Physical Review Letters, 1986A spherical model of Ising spins, placed on sites that are arranged in a cluster hierarchy, is studied. For the ferromagnetic transition, the critical exponents are found to have nonuniversal values in a certain range of system parameters, while they assume classical values in another range. Correlation functions show a behavior which is very different

Hierarchical Multiple Stellar Systems
2017In astrophysics of hierarchical multiple stellar systems there is a contradiction between their maximum observed multiplicity (up to seven) and its theoretical limitations (about five hundred). To search for the hierarchical systems of high multiplicity we have analyzed modern catalogues of wide and close stellar pairs.
